Fitting USB gps dongle inside rpi case... #33104
Hi Astronerd,
Take a look at this page for example : www.hobbytronics.co.uk/usb-connector-pinout
Vcc and gnd are easy to guess, maybe lookong at the other side of the pcb can help on Tx and Rx.

Franck

Yes there is a chip and other bits, but nothing that tells me what I need to know about removing the USB plug and wiring directly to the pins on the rpi3... :)

or, you could find another GPS module and do something like blog.whatgeek.com.pt/2015/03/connect-a-gps-to-the-raspberry-pi/

Now, yes that was my other option using one of these

www.hobbytronics.co.uk/gps-gp-20u7

It was just that I already had the USB dongle and a soldering iron... :)

According to the G7020-KT datasheet ( innovictor.com/pdf/UBX-G7020-Kx_DataShee...01)_Confidential.pdf section 6.1.1) , pin 8 is for usb_DM (D-) and pin 10 is for usb DP (D+).
According to the usb connector design central pin 2 is for D- and pin 3 is for D+, pin 1 is for vcc and pin 4 is for gnd
So if I not wrong this shoudl be something like this :


Please double check vcc and ground before plugin !!

Hi AstroNerd and happy new year!

I am very curious how it works - I would have thought, but do not know, that using the GPIOs of the Pi instead of the USB interface will require another driver that addresses the Pi‘s GPIOs. This is why I was pointing you to the astroberry-diy repository. However, could be that in your case, specifically for the TX/RX and V, GND it does not matter.

It might be necessary to also update the file /etc/default/gps (or similar).

Best, Helge

Happy new year to you too.. :)
Hmmm, you may be correct, I am no expert when it comes to the software side of things, I was just assuming, maybe wrongly, that it would just work the same a plugging a USB version in....plug and play as it were... )

I would recommend an alternative solution and install a serial GPS breakout board such as this one from Adafruit.
Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz updates
It is not difficult too install with a some basic skill and configured with GPSD. The external antenna is optional, but does improve the signal greatly. Orientation makes a big difference, ideally aim the breakout board straight up to the sky, or the antenna if you use that.

PHD2
Adafruit Motor Hat shield
Adafruit GPS Module
Generic Bluetooth Joystick.
Startech 7 port powered USB Hub.
